Technical note

What changes when you convert OBJ to DWG

Converting OBJ to DWG can produce two different files. With Create 2D projection switched off, the DWG receives the model itself as 3D geometry, which a CAD program can orbit and view from any side. With it switched on in the 3D formats loading settings, the DWG receives a flat view instead: isometric, top, front or side, with hidden edges dashed or removed. Neither version carries dimensions, a title block or section views, so treat the result as the start of a drawing rather than a finished sheet. An OBJ model is often a set of files rather than one: the geometry in the .obj, its materials in a .mtl file next to it, and textures as separate images. The .obj on its own describes shape only, so copy the whole set together whenever colour and texture matter.

3D Workflow

From 3D model to 2D drawing

Converting OBJ to DWG usually means getting flat views out of a 3D model. reaConverter generates them in batch, with no CAD seat on either side.

  • Choose an isometric, top, front or side 2D projection, with hidden edges dashed or removed
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs

The program's interface is refreshingly simple and intuitive. The entire process is streamlined to just a few steps: specify your source files, set an output folder, and you're done! Batch processing works flawlessly too. An excellent tool that makes file conversion effortless.

I inherited a mess of DWG files from a previous engineer – all in different versions. reaConverter batch‑converted them all to a single, clean DWG format (2018) with no errors. It even fixed some corrupt headers. This tool is a miracle worker.

When I switched from Mac to Windows, I couldn't open my old DWG files. reaConverter saved me – it converted them all to PDF and JPG with perfect scaling. Now I can view my CAD portfolio on any device. Thank you for making cross‑platform work possible!

The proliferation of niche formats like DWG creates unnecessary hurdles. After wasted hours on forums, I discovered this lean converter that delivers single-purpose excellence—precisely the 'no nonsense' solution CAD beginners require.
